Enhancement of Heat Transfer by Ultrasound: Review and Recent Advances

The following paper summarizes some applications of ultrasonic vibrations regarding heat transfer enhancement techniques. In several industrial applications, the use of ultrasound is often a way to increase productivity in the process itself, but also to take advantage of various subsequent phenomena. The relevant example brought forward here concerns heat exchangers, where it was found that ultrasound not only increases heat transfer rates, but might also be a solution to fouling reduction.
